How to Use Terabyte Image for DOS
(Click any image for full-size screenshot.)
In this illustration, the Image for DOS utility bundled within the BootIt boot manager will be used to backup the system's OS partition. The image will be stored on a secondary hard disk, and will include a backup of only the OS partition with no additional partitions.

Step 1:
From the BootIt Bare Metal desktop, click the "Disk Imaging" icon to launch the Image for DOS program.

If you are booting from stand-alone "Image for DOS" boot media, boot the program and continue with Step 2.

Step 2:
Select [Backup], and click [Next] to continue.

Step 3:
This tutorial will do a full backup of only the OS partition, so select [Full Backup], and click [Next] to continue.

Step 4:
Now select the source partition.

First select the standard BIOS interface, ...

Step 5:
... then the primary boot disk, ...

Step 6:
... and finally the OS partition to be backed up.

Step 7:
Next, select the destination location on which the backup image will be stored.

We're backing up to a secondary hard drive, so select "File (direct)", ...

Step 8:
... on the standard BIOS interface, ...

Step 9:
... on the secondary hard disk, ...

Step 10:
... and select the storage partition.

If the hard disk contains multiple partitions, there will be more than one partition listed here.

Select the appropriate partition and continue.

Step 11:
Give the backup a name, and navigate the folder structure on that partition, ...

Step 12:
... to the folder in which the backup image will be stored.

In this example, the backup image will be named \Backups\Terabyte\IFD-test-image.TBI in the DATA partition on Hard disk 1.

Step 13:
If desired, add a description for the backup image, and set the maximum size of each piece of the image file in a multi-file image set.

(I prefer to split large images into sets of 2GB files. That is a convenient size to store on linux or FAT32 volumes if need be, or for copying to DVDs when archiving old images.)

Step 14:
Click the [Start] button to begin the backup process.

Step 15:
Allow the backup process to continue to completion.

Step 16:
When the process has completed, close the windows and exit the program.
